RECREATIONS OF A LIGHTKEEPER. 



Notes on the Natural History of the Bell Rock. By J. M. 



CampbeIvTv. With an Introduction by James Murdoch. Edin- 

 burgh: David Douglas, 1904 Pp. xv. + ii2. Price, 31. dd. net. 



The author of this pleasant little book has been for nine years assistant 

 at the famous Bell Rock lighthouse, off the east coast of Scotland. During 

 this time he has made good use of his opportunities in observing the 

 animals haunting the reef, and a few glances at the volume show us that 

 he has recorded his observations vividly, and not without literary skill. 

 All the world knows in how many ways we are indebted to the brave 

 men who spend so much of their lives on these lonely rocks. The 

 recently-published work on bird migration, both in Scotland and 

 Ireland, had been impossible without the lighthouse keepers' willing 

 help. Naturalists will gladly welcome, therefore, this modest but 

 valuable contribution to the zoology of the sea. 



NOTES, 



BOTANY. 



A rare Alga in the Upper Bann. 



Cladophora {Conferva) cegagropila is thus noted in Flora HibernLa, Part III., 

 p. 228 (1836): — "In lakes, very rare. Connemara ; J. T. Mackay,'' and I 

 have no information of there being any subsequent Irish record. Its 

 occurrence, therefore, in the rocky bed of the River Bann at Knockna- 

 gor, Co. Down, where it was noticed in July last, may have some interest. 

 It grows in large, flat, smooth patches, only the tips of the densely com- 

 pacted, olive-green branches appearing above the fine, sandy deposit in 

 which it is embedded. The usual habitat seems to be moorland lakes, 

 and nowhere, perhaps, is it often seen m situ, but, when fully developed, 

 it becomes detached and rises to the surface in globose masses, varying 

 in size up to four inches in diameter. I have to thank Canon lyctt and 

 Mr. William West for their kindness in examining specimens submitted 

 to them, and for information which they have obligingly supplied.

Sligo Ferns. 



I see by the September issue that Hymenophylltim unilaterale is recorded 

 among the list of interesting plants found during the Field Club visit to 

 Sligo. It may be of interest to record that some two or three years ago 

 I found both H. unilaterale and H. tunbridgense in the habitat given by
